## Collections
- `data_search_j_collection.jsonl.bz2` (Japanese subtask)
- `data_search_e_collection.jsonl.bz2` (English subtask)
- Each line of these files is a dataset in the collection, and is in the JSON format
- Each dataset may contain multiple data, which are in `data` field
- Each data is stored in a file whose name is described in `data_filename` field
---
- `data_search_j_data.tar.bz2` (Japanese subtask)
- `data_search_e_data.tar.bz2` (English subtask)
- All the data in the datasets are included in these files
- These files are NOT included in Google Drive. Please visit https://ntcir.datasearch.jp/data/ to download the data files.

- `checksums.txt`
- MD5 hash values of `bz2` files are included
## Training queries for NTCIR-15 Data Search
- `data_search_j_train_topics.tsv` (Japanese subtask)
- `data_search_e_train_topics.tsv` (English subtask)
- Training queries, by which participants are expected to develop systems.
- Each line contains an ID and a query string separated by TAB
## Test queries for NTCIR-15 Data Search
- `data_search_j_test_topics.tsv` (Japanese subtask)
- `data_search_e_test_topics.tsv` (English subtask)
## Training qrels for NTCIR-15 Data Search
Relevance judgments for training queries.
- `data_search_j_train_qrels.txt` (Japanese subtask)
- `data_search_e_train_qrels.txt` (English subtask)
- The same format as that used in the NTCIR WWW tasks
- `[QUERY_ID] [DOC_ID] [REL_LEVEL]`
- e.g. `DS1-J-0002 000031519435 L2`, meaning that dataset `000031519435` is highly relevant (`L2`) for query `DS1-J-0002`.
## Test qrels for NTCIR-15 Data Search
Relevance judgments for test queries.
Documents from the official runs were judged.
- `data_search_j_test_qrels.txt` (Japanese subtask)
- `data_search_e_test_qrels.txt` (English subtask)
## Extra Qrels for NTCIR-15 Data Search
Relevance judgments for test queries.
Documents from the extra runs were judged.
- `data_search_j_extra_qrels.txt` (Japanese subtask)
- `data_search_e_extra_qrels.txt` (English subtask)
## All Qrels for NTCIR-15 Data Search
These are sets of qrels including the test qrels and extra qrels.
- `data_search_j_all_qrels.txt` (Japanese subtask)
- `data_search_e_all_qrels.txt` (English subtask)
## Training queries for NTCIR-16 Data Search
Training and test queries used in NTCIR-15 Data Search,
which could be used as training queries in NTCIR-16 Data Search 2.
More precisely, `data_search_2_*_train_topics.tsv` is a union of
`data_search_*_train_topics.tsv` and `data_search_*_test_topics.tsv`.
- `data_search_2_j_train_topics.tsv` (Japanese subtask)
- `data_search_2_e_train_topics.tsv` (English subtask)
## Training qrels for NTCIR-16 Data Search
